Default Spice model for Toshiba 2sa1941/2sc5198?

Hi all,

Does anybody have spice models for the Toshiba 2SA1941 and 2SC5198 output transistors? I have searched everywhere on the net but can only find the datasheets.

I need those for a small amp project, more about that later....

I am also looking for models for 2SB772 and 2SD882 (KSB772/KSD882).

Please advice, thank you in advance!

Have you got it?
I can't make the model netlists that I have to work.

I managed to find a model for 2SC5198 but not for the complementary 2SA1941.

.MODEL Q2SC5198 NPN(IS=10.000E-15 BF=105 VAF=100 IKF=10.000E-3 XTB=1.5 BR=.1001 VAR=100 IKR=10.000E-3 ISC=10.000E-15 CJE=2.0000E-12 CJC=412.95E-12 MJC=.33333 TF=608.00E-12 XTF=10 VTF=10 ITF=1 mfg=Toshiba)

I also got the data for 2SB722 and 2SD882:

.model Q2sb772 PNP(Is=282f Xti=3 Eg=1.11 Vaf=100 Bf=213.6 Ise=1.659p Ne=1.787 Ikf=6.472 Nk=.7894 Xtb=1.5 Var=100 Br=39.18 Isc=12.72p Nc=1.637 Ikr=.1652 Rc=64.89m Cjc=145.6p Mjc=.2985 Vjc=.3905 Fc=.5 Cje=255.3p Mje=.5064 Vje=1.615 Tr=10n Tf=1.927n Itf=6.218 Xtf=0 Vtf=10)

.model Q2sd882 NPN(Is=282f Xti=3 Eg=1.11 Vaf=100 Bf=200.7 Ise=288.7f Ne=1.368 Ikf=20 Nk=1.235 Xtb=1.5 Var=100 Br=52.37 Isc=8.515p Nc=1.527 Ikr=.2617 Rc=15.88m Cjc=166.3p Mjc=.4069 Vjc=.3905 Fc=.5 Cje=291.8p Mje=.3606 Vje=.75 Tr=10n Tf=1.551n Itf=1 Xtf=0 Vtf=10)

Please look out for 2SA1941, thank you!
